Rihanna is one crazy girl, I tell you! The tattoo obsessed, free spirit got some fresh ink added to her body this week at the Shamrock Social Club Los Angeles, and get this, she tatted the words “Thug Life” across her knuckles. Ummm…..why??? Check out the photo she tweeted below:

“All these bitches screaming that 2pac back ♫ #THUGLIFE,” she tweeted.

To top it off, Ri Ri tweeted out another photo in which she appeared to be getting another tat on her back from famed tattoo artist, Mark Mahoney, all the while holding a beer bottle. Classy!

This marks tattoos #15 and #16 for the Bajan princess, who already has her best friend’s birth date on her shoulder and another on her chest that reads “Never a failure, always a lesson.” I’m really started to feel like she’s addicted to tattoos!

While at the tattoo parlor, she also ran into Grindhouse actor, Danny Trejo. Now that’s “Thug Life”!!!
